BACKGROUND The diagnosis of left ventricular hypertrophy (LVH) in the presence of the left bundle branch block (LBBB) is difficult. In our study we compared commonly used ECG criteria with left ventricular mass index (LVMI) calculated during cardiac magnetic resonance imaging (CMRI) to verify their clinical value or the need to recalibrate. METHODS CMRI and ECG data of 36 patients were includ...

The new IMERG and GSMaP-v6 satellite rainfall estimation (SRE) products from the Global Precipitation Monitoring (GPM) mission have been available since January 2015. With a finer grid box of 0.1◦, these products should provide more detailed information than their latest widely-adapted (relatively coarser spatial scale, 0.25◦) counterpart. Integrated Multi-satellitE Retrievals for GPM (IMERG) a...

We present a case of wide-complex tachycardia with negative concordance in the precordial leads and a qR pattern in V6, in a 42-year-old man with risk factors for coronary artery disease, in whom the electrocardiogram criteria were apparently fallible. This case highlights the key contribution of the electrophysiological study in rendering correct diagnosis.

This paper presents an overview of backwards and forwards compatibility between Versions 6 and 7 of the SAS System and is intended to be used as a reference in determining what manner of access is allowed. Furthermore, this paper takes into account differences in compatibility between the Base SAS System and when products such as SAS/CONNECT and SAS/SHARE are used. SAS I/O Services The I/O Se...

BACKGROUND Ventricular fibrillation (VF) has been proposed to be maintained by localized high-frequency sources. We tested whether spectral-phase analysis of the precordial ECG enabled identification of periodic activation patterns generated by such sources. METHODS AND RESULTS Precordial ECGs were recorded from 15 ischemic cardiomyopathy and 15 Brugada syndrome (type 1 ECG) patients during i...

At least 20 different isoforms of the human CD44 lymphocyte-homing receptor/hyaluronan receptor have been described to date that arise from the differential splicing of up to 10 alternative exons (termed v1-v10) encoding the membrane-proximal extracellular domain. Although numerous analyses at the mRNA level have indicated tissue-specific expression of CD44 variants, few analyses have been perf...

BACKGROUND The importance of vagal tone on cardiac function and cardiovascular mortality is well established. Although the presence of an enhanced cardiac vagal tone (CVT) is frequently diagnosed using the 12-lead resting electrocardiogram (ECG) in daily practice, most of the proposed criteria have been determined on an empirical basis. Our objective was to evaluate the effects of pharmacologic...

INTRODUCTION AND OBJECTIVES The goal of this study was to analyze the value of electrocardiography in predicting the site of the lesion in the left anterior descending coronary artery, in relation to the first septal and the first diagonal branches, in patients with acute anterior myocardial infarction. METHOD Ninety consecutive patients who were admitted to the coronary unit with acute anter...

iate discriminant analysis did not select V5 or V6 as leads in which ST-segment shift distinguished patients with acute LMCA obstruction from patients with acute obstruction of the left anterior descending coronary artery (LAD). Therefore, we do not consider ST-segment depression in leads V5 and V6 to be a characteristic finding in “LMCA AMI patients.” The findings of our patients indicated tha...
